Gaillardia plant named ‘DGAL902’

ABSTRACT

A new and distinct  Gaillardia  cultivar named ‘DGAL902’ is disclosed, characterized by a distinctive lemon yellow flower, somewhat compact plant habit, good branching and abundant flowering. The new variety begins blooming early in the season and flowers over a long period of time. The new variety is a  Gaillardia , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Gaillardia pulchella.

Variety denomination: ‘DGAL902’.

BACKGROUND OF THE INVENTION

The new Gaillardia cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Gaillardia varieties for ornamental commercial applications. The cross resulting in this new variety was made during August 2005.

The seed parent is the unpatented, proprietary seedling variety referred to as Gaillardia pulchella ‘GAI-31’. The pollen parent is unknown, as the crossing resulting in ‘DGAL902’ was an open pollination, with unidentifiable pollen parents. The new variety was discovered in July 2006 by the inventor in a group of seedlings resulting from the 2005 crossing, in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar ‘DGAL902’ by vegetative cuttings was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel in February 2007 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DGAL902’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DGAL902’ These characteristics in combination distinguish ‘DGAL902’ as a new and distinct Gaillardia cultivar:

-   -   1. Somewhat compact habit     -   2. Highly floriferous     -   3. Long flowering season     -   4. Good branching     -   5. Early blooming     -   6. Unique lemon yellow flower color

Plants of the new cultivar ‘DGAL902’ are similar to plants of the seed parent, Gaillardia pulchella ‘GAI-31’ in most horticultural characteristics, however, plants of the new cultivar ‘DGAL902’ produce more flowers and branches on a more compact plant than ‘GAI-31’.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DGAL902’ are comparable to the variety Gaillardia pulchella ‘Torch Red Embers’, patent status unknown after reasonable search by the applicant. The two Gaillardia varieties are similar in most horticultural characteristics, however, the new variety ‘DGAL902’ differs in having more flowers per plant, different colored flowers and a more compact, and spreading plant habit. Additionally, ‘DGAL902’ has semi-double flowers, compared to the double flowers of ‘Torch Red Embers’.

Plants of the new cultivar ‘DGAL902’ can also be compared to the commercial variety Gaillardia ‘BALTORYELL’ U.S. Plant Pat. No. 15,966. These varieties are similar in most horticultural characteristics, however plants of ‘DGAL902’ produce lighter yellow flowers than ‘BALTORYELL’. ‘DGAL902’ produces semi double flowers, whereas ‘BALTORYELL’ produces fully double flowers. Additionally, ‘DGAL902’ has more flowers per plant, and a more compact, spreading plant habit.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DGAL902’ grown in a greenhouse, in a 12 cm pot.

FIG. 2 illustrates in full color a close up of a single flower of ‘DGAL902’.

Age of the plant photographed is approximately 8 weeks from a rooted cutting. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
